Abstract

The invention discloses a joint synovial membrane biopsy needle structure and a usage method thereof. The joint synovial membrane biopsy needle structure comprises a sleeve, a cavity, a connecting sleeve, a mounting plate, a connecting pin, a liquid discharging hole, a bolt, a puncture needle, a positioning hole, a sliding pin, a spring, a threaded blade and a conical needle head, the invention discloses a joint synovial membrane biopsy needle structure and a usage method thereof. The synovial fluid extractor is ingenious in structure, powerful in function and easy to operate, joint effusion,namely synovial fluid, can be extracted by using the synovial fluid extractor, synovial membranes can also be extracted, the synovial fluid extractor has an instructive effect on diagnosis and treatment of arthritis, and in addition, synovial membrane tissue extraction plays a huge role in promoting scientific research of arthritis in scientific research.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a structure of a joint synovial biopsy needle and a method for using the same. Background technique [0002] The synovial membrane (synovial cell) is the inner layer of the joint capsule, light red, smooth and shiny, thin and soft, composed of loose connective tissue. The connective tissue membrane that covers the inside of the joint capsule. [0003] The traditional synovial biopsy operation is traumatic and has a high risk of infection. The puncture of the joint cavity can only extract the joint fluid, and it is difficult to remove the synovial tissue, which makes it difficult to diagnose the type of arthritis. In view of the above defects, it is necessary to design a synovial biopsy. Structure of a membrane biopsy needle and method of use thereof. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a structur...
